Solo planner
To plan, in cities, alone. There is an itinerary, and it was negotiated with nobody.
In detail
PCSYou move through a city at your own pace with no one to consider. Three hours in a museum and nobody hurries you; skip lunch and you owe no explanation.
The plan is tight because you dislike failure. Alone, any problem is yours to solve, so you shrink the odds in advance. Bookings and fallbacks are always in place.
The risk is that the trip becomes an assignment. There's satisfaction in having executed it, but almost nothing unplanned happens, and so there are no stories afterwards.

Clashes with
Just goes — Nothing decided, in nature, with people. Where to is settled after everyone's in the car.
